Application filed m 15, 1920. serial no. 396,397.

To all whom it may concern:

New York, have invented certain new and useful Improvements in Cylinder-Linings for Engines; and I do declare the following to be a full, clear, and exact description of the invention, such .as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in linings for the cylinder bores in the engine block of automobile engines, although it is not to be restricted to this particular use since it may be just as effectively used with various other types of engines.

One of the objects of the invention is to generally improve upon devices of this class by the production of one which is extremely simple and effective and is such that it may be easily and readily inserted and remored- Another object of the invention is to provide a removable lining for cylinder bores which includes a detachable locking ring which is screw-threaded and engages screwthreads on the lining, this ring having novel means associated with it for positively preventing accidental rotation thereof which would permit displacement of the lining, this means being associated with one or more of the other like rings.

A further object of the invention is to'provide a lining of the above mentioned type which is such that it will be prevented.

against possible movement when properly placed in position thus overcoming wear to which it would be subjected if permitted to move.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings forming part of this specification and in which like numerals -are employed to designate like parts throughout ,the same:

F 1g. 6 is a detail sectional View of the retaining ring.

Fig. 7 is an enlargeddetail view of the lower end of the lining, showing more clearly the manner in which it coacts with the cylin der bore. 1 In thedrawings, wherein for the purpose of illustration, is shown a preferred embodiment of my invention,the letter A designates a portlon of a conventional form of automobile engine cylinder block. This block shown 1s that of a Ford, however, Iwish it to be understood that my lining may 'be used in the bores of various, and probably all types of cyhnder blocks including those of steam engmes. In order to permit the use of my device, it is necessary to ream the opposite ,ends of the cylinder bores as shown at S toprovide shoulders. Some of the bores may be provided with similar shoulders and it may be unnecessary to form them by reaming as I have suggested above. viding the bores with these shoulders I also provide them at their upper ends with short vertical slots B, which serve a'purpose to be hereinafter set forth. I am assuming that the cylinder block is disposed vertically, hence I may conveniently refer to the upper and lower endsof the cylinder bore.

My improved lining, designated by the numeral 1, comprises a sleeve of'a S128 to fit snugly in the cylinder bore in the block A,

the sleeve being equipped at its upper end with a laterally extending flange 2, the lower face of which is beveled for efi'ective contact ternal screw-threads 4 with which the screwthreads of a retaining ring 5 contact, the' I latter having its inner face also beveled for effective engagement with the beveled shoulder at the lower end of the cylinder bore. Inaddition to this, it has extending from its lower face, a plurality of closely spaced apertured projections 6, one of the functions of which is to permit the ring to be rotated for the purpose of tightening and loosening it, this being done with any suitable kind of a tool. These lugs also serve another and extremely important function. To explain, they permit a wire 8 to be passed to the apertures therein and throughthe apertures in the lugs on oneor more of the other ringsas illustrated in Fig. 2, the ends of the wire being tied so that relative rotation of the rings will be absolutely prevented. With this construction the linings cannot possibly become displaced or loose enough to interfere with the operation of the piston, which would subject them to considerable wear in case they were loose. Emphasis is to be laid on this feature of construction which is novel and new sofar as I am aware.

that the retaining ring and lateral flange carried by the lining prevents the latter from moving either up or down, and by "provision of the lateralprojection 3 which prevents ropassed downwardly through the bore and permitted-to roject beyond theinnerend of-the lower s oulder. Then, the retaining ring is screwed on and tightened by use of a suitable tool which will be permitted to enrejections 6'-f0r the purpose of gage the rotating t e ring; -After twoor more of the rings "have been screwed on the wire 8 is passed through the apertures in theprojection 6 in the manner already described in order to prevent relative rotation of the retaining rings, thus locking them in effective positionand'preventing accidental rotation which might otherwise occur.

From the,foregoingdescription it will be seen that I have devised an extremely sim-' ple, effective, and inexpensive method of keeping. the cylinders of a motor car in perfeet condition with very little cost to the owner of the car. My linings provide a remedy for insuring excellent compression which is lost in worn cylinders which must necessarily be re-bored in order to secure this result. Re-boring of the cylinders is a difficult and expensive op eratlon and the replacing of a new motor block is likewise expensive and when the cylinders are-rebcred a whole new set of over-sized piston rings and pistons must be sup lied which of course adds to the expense. y the pro- In view of the factremovable lining, these disadvantages and expenslve operatlons are entirely overcome. In case the linings become badly worn, they may be easily and readily re-- skilled in the art to which this invention ap-,

pertains, to obtain a clear understanding of the same. Therefore a more lengthy description is deemed unnecessary.

Since probably the best results may be ob. tained with the construction and arrangement shown, this is to be taken'as a preferred embodiment ofmy invention. However, I wish it to be understood that minor changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or thescope of the subjoined claims.

I claim:

1. In a removable cylinder lining for en gines, the combination with an engine block providedwith a cylinder bore in the wall of which is a vertical groove and at the opposite ends of which are shoulders, of a lining fitted into the bore, provided with a laterally extending lug fitting into said groove, and at its ends with lateral flanges engaging said shoulders, one of said flanges being detachable to permit insertion and removal of the lining.

2. In a removable cylinder lining, the combihation with an engine cylinder block provided with a cylinder bore beveled at its opposite ends to provide shoulders; of a re being dprovided at one end with a lateral bevele flange engaging the upper shoulder and bein screw threaded at its opposite ends, an lnternally screw-threaded beveled ring engaging said threaded end of the ling and the wall of said bore to prevent rotation of the lining. v

3. In an engine cylinder lining, the combination with a cylinder block provided with a vertical cylinder bore having shoulders at its opposite ends, a sleeve disposed in the bore, being provided at one end with a shoulder engaging said first shoulder, and at its opposite end with screw-threads, a screw-threaded retaining ring fitted on the screwthreaded end of said sleeve and engaging the adjacent shoulder on the cylinder block, said ring having a plurality of closely spaced lateral projectionsthereon by means of -which it ma be rotated.

4. In an engine cyllnder lining, the combination with a cylinder block including a .vision of my novel, simple and inexpensive movable lining fitted into the bore, the same and 'coacting means between the latter 1 plurality of cylinder bores having shoulders at one end, linings fitted into said bores, being screw-threaded at one of their ends, ooacting means between their opposite end and said bores for retaining them against movement in one direction, screw-thread rings. engaging the threaded ends of said sleeves, said rings carrying a plurality of laterally extending apertured lugs for rotating them, and a wire passing through the 10 apertures in said lugs to lock said rings against relative rotary movement.

In testimony whereof I have hereunto set my hand.
